I think we need at least one specific current example of an "umbrella
specification" to
illustrate and support our current text in ViS (since this is a new term to
be in ViS but
not in SpecGL, and we have examples of other aspects in ViS
already). If there
is no such example of an "umbrella specification" to be found, then what is
our motivation for
describing an "umbrella specification" (to indicate current "best practice"
or to point to
a reference to aspire to for the future)?
Thanks and best wishes

PS - Is the reference to XML Schema Part 2 in the current text meant to be such
an example of an umbrella specification? If so, than the reference should
be explicitly labelled as such.
It is not clear to me from reading the current text that XML Schema Part 2
is in fact an example of
an umbrella specification; does the use of the word "It" before the
reference refer to "specification" (defined
previously in the same section) or to "umbrella specification" (not defined
previously in that section (but
following?))?
The reference to OWL implies that an umbrella specification could be
created in the future,
not that one exists now.
